| 9 | # Poky-tiny is intended to define a tiny Linux system comprised of a | ||
| 10 | # Linux kernel tailored to support each specific MACHINE and busybox. | ||
| 11 | # Poky-tiny sets some basic policy to ensure a usable system while still | ||
| 12 | # keeping the rootfs and kernel image as small as possible. | ||
| 13 | # | ||
| 14 | # The policies defined are intended to meet the following goals: | ||
| 15 | # o Serial consoles only (no framebuffer or VGA console) | ||
| 16 | # o Basic support for IPV4 networking | ||
| 17 | # o Single user ash shell | ||
| 18 | # o Static images (no support for adding packages or libraries later) | ||
| 19 | # o Read-only or RAMFS root filesystem | ||
| 20 | # o Combined Linux kernel + rootfs in under 4MB | ||
| 21 | # o Allow the user to select between eglibc or uclibc with the TCLIBC variable | ||
| 22 | # | ||
| 23 | # This is currently a partial definition, the following tasks remain: | ||
| 24 | # [ ] Integrate linux-yocto-tiny ktype into linux-yocto | ||
| 25 | # [ ] Define linux-yocto-tiny configs for all supported BSPs | ||
| 26 | # [ ] Drop ldconfig from the installation | ||
| 27 | # [ ] Modify the runqemu scripts to work with ext2 parameter: | ||
| 28 | # runqemu qemux86 qemuparams="-nographic" bootparams="console=ttyS0,115200 root=0800" | ||
| 29 | # [ ] Modify busybox to allow for DISTRO_FEATURES-like confiruration | ||
